Raiders add cornerback Porter

Oakland coach Dennis Allen was his position coach in New Orleans. Porter left the Saints to sign a one-year deal with Denver last offseason.

He started the season as a starter but dealt with the affects of a seizure suffered in the summer.

Porter has eight career regular-season interceptions, plus two in the postseason, including a pick of Peyton Manning in Super Bowl XLIV that he returned 74 yards for a touchdown to seal the Saints’ 31-17 victory over the Indianapolis Colts.
